What you are seeing about the using of bitcoin to make option for fiat is just temporary. Adoption is going to happen through getting it down in the book and the government endorse it as documented, then fear of using it will go out from majority of the nation who are banning it.
Here's some proof that the government already supporting it, and that is by regulating exchanges which we cash in and cash out our money.
Maybe other platforms will be followed soon but you can't expect they'll be able to regulating everything instantly.
if today we raise the issue of daily use of cryptocurrency and in particular bitcoin, then the really obvious problem consists of poor infrastructure development, but the main problem is precisely the lack of government regulation, since every businessman must submit reports to the tax service, but the rules for declaring cryptocurrency are all not yet available.
